A Greene County man was being held in jail on assault charges related to a road rage incident on a Washington County interstate.
State police in Washington said Michael Shelleby, 62, of Holbrook, threatened John Poprosky, 50, of West Newton, with a gun on Interstate 79 just north of Interstate 70 in South Strabane on Friday afternoon.
Police said the incident began when both drivers were traveling in the left lane and Mr. Shelleby "did not want to let the victim pass."
Mr. Poprosky tried passing in the right lane, police said, but Mr. Shelleby sped up to block him. Mr. Poprosky slid back over into the left lane. When he tried to pass again on the right and the vehicles were side-by-side, police said, Mr. Shelleby reached across the passenger seat, rolled down the window and displayed a handgun.
Mr. Poprosky called police, who stopped Mr. Shelleby and recovered the weapon - a .380-caliber Kel-Tec semiautomatic.
Troopers arrested Mr. Shelleby on charges of aggravated assault, simple assault, reckless endangerment and harassment.
He was jailed on a $15,000 bond.
